GeoBroker: A Pub/Sub Broker Considering Geo-Context Information

Abstract

The majority of today’s pub/sub brokers only focus on data content when deciding where to distribute data. In this paper, we introduce the GeoBroker pub/sub broker software that additionally considers the geo-context associated with data producers and consumers. As a result, data consumers only receive relevant messages which preserves bandwidth and compute power while data producers can use the geo-context of clients to control data distribution, e.g., for enhanced privacy or as an alternative to credential-based authentication.
